zIf you store batteries for a long period of time (about 1 year), it is recommended that you deplete the batteries in the camera and to then store them at room temperature (0 to 30 °C/32 to 90 °F) in low humidity. Storing them in a fully charged condition can shorten their lifespan or degrade their performance.
Again, if you do not use batteries for more than 1 year, fully charge them once a year and fully deplete in the camera before storing them.
zIf the battery usage time has become considerably low despite wiping the terminals and charging them until the battery charger indicator remains lit, this may indicate that the batteries have reached the end of their lifespan. Replace them with new batteries. If you are purchasing new batteries, look for Canon
zLeaving batteries in the camera or charger may result in damage from battery leakage. When not in use, remove the batteries from the camera or charger and store them in a cool, dry location.
zIt takes approximately 4 hours 40 minutes for the charger to fully recharge the batteries after they have been fully discharged. When two batteries are placed on each side of the charger, recharging will take approximately two hours (as determined by testing at Canon facilities).
Charge batteries in an environment where the temperature is in the range of 0 to 35 °C (32 to 95 °F).
zThe charging time varies according to the ambient temperature and to the battery charge state.
zThe battery charger may emit noise while charging. This is not a malfunction.
